IMPRovBD nxTENsIoN-TABLE SLIDE.

The Schedule referred to in thesev Letters Patent and making-part ofthe same.

'strengthen them.

On reference to the accompanying drawing making part of this specitication- Figul'e 1 is a perspective view of the table extended;

Figure 2 is4 au enlarged viewof one end of the table;

Figure 3 shows a perspective of the runners and brasses4 or guides; y

Figure 4 is a sectional end view of the guides and runners; iand Figures 5 and 6 are perspective views ofthe guides. Similar letters refer to similar parts in vthe several views.

Heretofore stops, consisting of dowcls or round pins, haveheen used in connection with guides for the purpose of extending the table, but they ared'efective by reason ot' cutting too much of lthe material of the runners and want the essential element of strength.

My improvement consists of metal guides or stops on the runners.

I The guide A has tenons, a a, on its back, which take into corresponding mortises in ,the runner B, fig. 4; its inner surface also has tenons, af a', which take into corresponding mortises in the plate '0, which is fixed to the oppositerunner D; the upper and Ilower ends of Vthe guide A span the .ends ot' the plate C; the depending ends b. takev 'into grooves formed top and bottom of the runner I audthereby prevent the runners from separating -or spreading', and, colisequently, vstit'fens them.

Itwill be noticed, fig. 6, that the lnortises 'c in the plate C do not extend the entire length of it, but are Ystopped-off at a suitable distance to form buttiug pieces, d, for the ends of the tenons a of the guide A; when it is being opened its tenons burtt,.against the stops d, and prevent the further extension of the runner B without also extending the contiguous runner D. l Y V An angular buttng piece, E, is employed for closing the runners.

What I claim as my impro-rement is'- The guide A, provided with tenons a -a and a a',

` and' ends b b, and the plate C, when constructed as shown and described, in combination with the runners B and D of an extension't-ahle.

In tcstixnony'whereof I hereunto sign my .name to lthis specification inpresence of two subscribing witnesses.A L I j WILLIAM DONOGHUE.
